  • VERIFY:

    Outer straights are the HOTS
    Center straight is NEUTRAL
    Center round is GROUND

    So from either outer to center round or center straight= 120 VAC
    Center round to center straight= 0 VAC
    Outer straight to outer straight= 240 VAC

    Strongly recommend you get a AC VOLTMETER and make some measurements like shown in this pictorial.

    Make these measurements at the 120VAC RECEPTACLE where your SHORE POWER CABLE plugs into it.



    Since you have been using it already with no smoke it most likely is OK but I would want to know for sure. There are so many BAD STORIES on here where the son-in-law or best friend does the work. Its best to use the licensed and BONDED electrician so their insurance will pay the bill to replace all things that burns up when wired like the HOME systems are wired....

    Is a range not a home connection?
  • 50 Amp RV outlet should be wired exactly the same a range (stove) outlet.

    You will probably want the outlet ground to be placed on top.

    What's the difference?


    For me it was an additional $850!

    New TV's, New DVD, New Converter, New Microwave/Convection oven, and New Electrical Transfer Switch.

    And THEN got it wired up the correct way. Exspensive lesson learned.
